Hydraulic torque wrench systems
Designed for industrial maintenance, بناء, heavy lifting, and professional hydraulic applications.
أ hydraulic torque wrench system consists of a مضخة هيدروليكية, high-pressure hoses, and hydraulic torque wrench. The pump generates controlled hydraulic pressure, which drives the wrench to produce accurate and repeatable torque for tightening or loosening high-strength bolts.
LONGLOOD hydraulic torque wrench systems are widely used in industries such as wind power, زيت & غاز, البتروكيماويات, بناء السفن, power plants, heavy machinery, and steel structures, where precise bolt tightening is critical.
A complete hydraulic torque wrench system includes:
Hydraulic Torque Wrench
Converts hydraulic pressure into rotational torque
Provides accurate bolt tightening force
مضخة هيدروليكية
Generates hydraulic pressure
Controls torque output through pressure adjustment
High-Pressure Hydraulic Hoses
Transfers hydraulic oil between pump and wrench
Pressure Gauge
Displays hydraulic pressure
Allows accurate torque adjustment
Socket / Drive Accessories
Connects wrench to the bolt or nut
Choose a pump according to the torque wrench requirements.
Consider:
Required torque range
Operating pressure
Oil flow rate
Number of wrenches used simultaneously
Most industrial hydraulic torque wrench systems operate at:
Maximum Pressure: 700 حاجِز (10,000 رطل لكل بوصة مربعة)
مثال:
أ 700 bar electric hydraulic torque wrench pump can provide stable pressure output for high-precision bolting applications.
Before operation:
Check hydraulic oil level in the pump reservoir
Ensure oil is clean
Use recommended hydraulic oil
Insufficient or contaminated oil may cause:
Reduced torque accuracy
Pump overheating
Internal component damage
Connect the pump and wrench using high-pressure hoses.
Connection procedure:
Turn off the hydraulic pump
Connect the supply hose to the wrench
Connect the return hose to the wrench
Tighten couplers securely
Install protective dust caps when not in use
Important:
Never connect or disconnect hoses under pressure
Ensure hoses are not twisted or damaged
Use only hoses rated for 700 bar operation
Install the wrench onto the bolt.
Before operation:
Select correct socket size
Confirm wrench reaction arm position
Ensure the reaction point is stable
Check that the wrench is aligned correctly
The reaction arm must contact a solid surface to prevent movement during operation.
Hydraulic pressure determines the torque output.
إجراء:
Check the torque chart supplied with the wrench
Find the required torque value
Convert required torque into hydraulic pressure
Adjust the pump pressure regulator
Confirm pressure on the gauge
مثال:
If the torque chart indicates a specific pressure setting for a required torque value, adjust the pump until the gauge reaches that pressure.
Connect power supply
Turn on the pump
Select forward/retract mode
Pump sends hydraulic oil to the wrench
Wrench rotates and tightens the bolt
Release pressure after reaching the required torque
Close release valve
Operate pump handle
Monitor pressure gauge
Continue pumping until required pressure is reached
Release pressure after completing tightening
Recommended tightening process:
Place torque wrench on the bolt
Position reaction arm securely
Increase hydraulic pressure slowly
Allow wrench to complete the tightening cycle
Release pressure
Repeat cycles if required
For critical applications:
Use cross-pattern tightening
Follow specified bolt sequence
Confirm final torque value
After completing the operation:
Stop the hydraulic pump
